[F-18]Fluoromisonidazole ([F-18]FMISO) is a hypoxia imaging marker utilized in positron emission tomography. Novel FMISO precursors were prepared from a commercially available material, and several reaction factors that affect synthesis of [F-18]FMISO were examined to achieve a higher fluorination yield. [F-18]FMISO was obtained from radiosynthesis, followed by the hydrolysis of protecting groups with HCl. New 2-nitroimidazole precursor showed a higher [F-18]fluorination and a higher synthetic yield. This result provided alternative guidelines for the preparation of hypoxia imaging marker.
